phyphox 1.1.0

17.06.2019

Changes on Android and iOS

  • Phyphox is licensed under the GNU General Public License from this version onwards
  • Bluetooth Low Energy support
  • Bluetooth Experiments included: Generic heart rate sensor, generic HID mouse, PocketLab One, PocketLab Voyager, Sensirion Smart Humigadget, Texas Instruments SensorTag CC1350/CC2650
  • Interactive graphs (zooming, picking points, linear fit)
  • New experiment: Applause meter
  • Multi-line plots
  • Bar charts
  • Color plots (used in spectrum experiments)
  • Open experiments from zip files or QR codes
  • Raw sensor experiments now feature a multi-line version
  • New languages: Chinese (simplified script), French, Vietnamese
  • Acoustic stopwatch has a new "many" tab , which allows measuring of an unlimited number of events, giving each interval and calculating the rate (Hz or bpm) and average interval of all events
  • Improvements to make the sonar more reliable
  • Performance optimizations for several experiments
  • Distance from start info for GPS-Experiment
  • Inclination experiment now features several different reference systems
  • Removed the libraries jquery and flot from the remote interface, which now uses chart.js instead
  • Remote interface now starts with a font-size recommended by the browser and allows changing the font size
  • Picking data points in the remote interface
  • The remote interface allows to show a single graph filling the full screen
  • Remote interface now communicates through a queue to avoid missed requests by the single-threaded webserver on the phone
  • Introduced a default color palette, which is used for coloring multiple graphs and can be referenced to by using names (red, blue, etc.) instead of RGB-values
  • Experiment configurations can be loaded directly from BLE devices
  • New device info report from menu on main screen
  • Add color to special categories (saved states and simple custom experiments)
  • Allow external experiments to define icon and category colors
  • Allow renaming of saved states
  • Use experiment title as default file name when exporting data, saved states or screenshots
  • Show state title in experiment info
  • Add hint to start button and add logic to hint bubbles, so they only show up until the user has used the specific function a few times
  • Fix: Wrong scaling of data in Doppler experiment due to outlying points
  • Fix: Consider available precision in remote interface to avoid retrieving the same value multiple times
  • Improve magnetic ruler for longer measurements
  • Fix inelastic collision experiment only working after pressing "reset"
  • Disable export and explain it to the user if an experiment configuration does not define an export

Changes on Android

  • Fix calculation of GPS height above geoid (MSL) if non-GPS satellite systems (GLONASs) are used
  • Vertical accuracy in GPS data if supported by some Android 8+ devices
  • Support temperature and humidity sensors
  • Support vendor-specific sensors by guessing their function by name
  • Improved performance by using native code for some operations
  • Improved Fourier transform performance by using the FFTW library
  • Allow screen rotation during measurement (now consistent with iOS)
  • Prevent adding identical experiments multiple times
  • Add notice when no address for the remote access is available
  • GPS now also uses network data by default and offers to force GPS only in the menu
  • Fix: Crash on malformed icon data
  • Fix: Sort categories case-insensitive
  • Fix loading experiments from URLs without query strings
  • Fix: Result response from webserver used broken JSON format.
  • Limit state title length

Changes on iOS

  • Complete rewrite of experiment parser. Much faster and much more stable when loading external experiments with errors.
  • Buffer rewritten. This should fix previous crashes in long-term measurements due to a race condition when accessing the buffers.
  • Respect save area guides to avoid drawing the UI in areas used by system buttons or the notch (iPhone X and similar)
  • Fix: Missing parts of a translation fall back to English defaults
  • Fix: Pick experiment language according to app language and avoid using unreleased languages already present in the experiment definition files
  • Fix: Re-saving states crashes the app
  • Fix: Power function fails for negative exponents

File format update to version 1.7

  • New graph types and multiple graphs
  • New Bluetooth Low Energy definitions
  • New "formula" analysis module
  • New "reduce" analysis module
  • New "map" analysis module
  • New attribute to enable analysis optimization (only re-run modules if their inputs have changed)
  • Label and unit can (and should) be separated for graphs to allow giving the right unit when reading a single data point
  • Colors can be names instead of RGB hex values
  • Value and info elements may now be colored
  • Temperature and humidity sensor types
